Key Words

• Full Duplex, Half Duplex

According to the direction of information transmission, serial communication includes Full Duplex and Half Duplex.

1. Full Duplex: Data is received and transmitted on different lines. Both sides can receive and send the message at the same time.

2. Half Duplex: Data is received and transmitted on one line. Both sides can’t receive/send the message at the same time.

• Point-to-point, Point-to-multiple and Multiple-to-multiple

1. Point-to-point: There are only one sender and one receiver on the transmission line.

2. Point-to-multiple: There are one sender and many receivers on the transmission line.

3. Multiple-to-multiple: There are many senders and receivers on the transmission line.

• Serial Transmission Speed

A bit per second is used to express the speed of the serial transmission.

• Format of the Serial Transmission

5. Inverter Parameters about Communication

1. Select the operating command of inverter

Sn-08= × × 0 × Sn-04= × × × ×

GS inverter operates according to the command from PLC.

Sn-08= × × 1 × Sn-04= × × 0 ×

GS inverter operates according to the command from circuit terminal

Sn-08= × × 1 × Sn-04= × × 1 ×

GS inverter operates according to the command from digital operator.

2. Select the frequency command

Sn-08= × × × 0 Sn-04= × × × ×

The frequency command is from PLC.

Sn-08= × × × 1 Sn-04= × × × 0

The frequency command is from control terminal 13 and 14 of inverter

Sn-08= × × × 1 Sn-04= × × × 1

An-01 is the frequency command.

3. Waiting for Communication If the RUN/STOP or frequency command comes from PLC and there is no communication, the digital operator of inverter displays “Comm. Stand by” and flashes. It will flash until SI-M option card receives data from PLC.

4. Operation of communication error

Sn-08= 0 0 × × The digital operator displays fault message and the inverter decelerates to stop according to Bn-02.

Sn-08= 0 1 × × The digital operator displays fault message and the inverter coasts to stop.

Sn-08= 1 0 × × The digital operator displays fault message and the inverter decelerates to stop according to Bn-04.

Sn-08= 1 1 × × The digital operator displays flashing alarm message and the inverter remains running.


6. Installation Procedures 1. Turn off the power supply of PLC and inverter, insert SI-M into

2CN. 2. Set DIP Switch of SI-M according to the communication

setting. 3. Connect PLC and SI-M. 4. Provide inverter with power and set parameter of inverter. 5. Provide PLC with power.

7. Modbus Communication Protocol 1. In Modbus protocol RTU mode, one message consists of slave

address, function code, date and CRC-16. All of which are sent in order. 3.5 characters identify the start and end of each message.

T1 T2 T3 T4* Slave Address

Function Code Data CRC-16 T1 T2 T3 T4*

* T1-T4: byte time

Bit format is shown below:

Start 1 2 3 4 5 6 7 8 Stop Stop

(1) Slave address

Set the address of each inverter according to S1 of SI-M interface card, with the range from 01 to 31. The entire message is sent from Master can be received by all the slaves connected together, but only the slave with identical message will execute.

(2) Function code

Function Code Function

03H Read the message of the Holding register 10H Write the message into the holding register

(3) Data

As each function code has different messages, we will discuss them in “Message Format”.


(4) CRC-16 CRC-16 Generation Procedure. A. Load a 16-bit register with FFFFH. Call this the CRC

register. B. Exclusive OR the first 8-bit byte of the message with the low

order byte of the 16-bit CRC registers, putting the result in the CRC register.

C. Shift the CRC register one bit to the right (toward the LSB), zero filling the MSB. Extract and examine the LSB.

D. If LSB is 0, repeat procedure C (another shift). If LSB is 1, Exclusive OR the CRC register with the polynomial value A001H.

E.Repeat procedure C, D until eight shifts has been performed. While this is done, a complete byte will have been processed.

F. Repeat procedure B-E to the following byte of the message until all bytes of the message is processed. Now, the value of CRC register is the CRC-16 data.

G. When the CRC is placed into the message, it upper and lower bytes must be swapped.

2. Response Message

(1) Please consult “message model” about response message. (2) If there is no response message, the inverter should send

message after receiving the order 20ms later. (3) The inverter will have no response message in the following:

A. While checking up the error (Parity error, Framing error, Overrun error or CRC-16 error) during receiving data.

B. The slave address of the message is not equal to that of SI-M interface card.


8. Message Format SI-M communication cards support two Modbus functions only.

01H Function-code fault Function-code of PLC is not 03 or 10H

02H Holding register code fault

Address of the holding register fault

03H The number of holding register fault

Read/write number of holding register overruns

21H Message setting fault Message setting overruns

22H Write mode fault

• PLC tries to write Sn, Cn during running • PLC tries to write parameters during UV • PLC tries to write parameters (except Sn-02,

Sn-03) during CPF04 • PLC tries to write parameters during dealing

the information • PLC tries to write Cn-02~08 when Sn-02 ≠ F or

FF • PLC tries to write message that only can be

read

31H CPU of inverter fault

• I/O PORT GUPX=1 • Internal RAM detection fault (55H,AAH) • External RAM detection fault (55H,AAH) • PROM and detection fault

32H DP-RAM fault 1

• Mode detection fault (CPF23) • Identify fault (CPF23) • Wait for INTL over 5s (CPF23) • BB circuit fault (CPF02) • NV-RAM, SRAM fault (CPF03)

33H DP-RAM fault 2 • BCC detection fault (CPF23)


11.Communication Example We can use PLC to control 7200GS inverter with address 05 by RS-232, RS422/485 communication mode, as follows: 1. Let the inverter forward run by 60Hz. 2. Let the inverter forward run by 30Hz. 3. Let the inverter reverse run by 30Hz. 4. Let the inverter coast to stop. Setting steps is listed as follows: 1. SI-M option card DIP Switch setting:

S1: 1 2 3 4 5 6 7 8 ON OFF ON OFF OFF - OFF -

Address 05 keep error into inverter S2: 1 2 3 4

OFF ON ON OFF

Slave Address 05H

Function Code 10H

High byte 00H Head Address Low byte 01H

High byte 00H Access Count Low byte 02H

Data Byte Count 04H

High byte 00H Data Value 1

Low byte 01H


Low byte 70H

Low byte 78H CRC-16

High byte 87H The 1st byte 0001H is transmitted to address 0001H of inverter for forward running.

The 2nd byte 1770H is transmitted to address 0002H of inverter for running at 60Hz.

• Frequency command is set with conversion 100/1Hz. And it needs

modifying to be hexadecimal. For example: If frequency command is 60Hz, 60 x 100 = 6000. The data written to inverter is 1770H (hexadecimal value of 6000)
